Project Goals
•Determine feasibility of linking existing NASA Earth Science products with empirical models of beach contamination.
• This effort will provide decision-makers with operational tools to gain a better situational awareness of potentially hazardous conditions in beach ecosystems.
•Better forecasting tools will potentially maximize the extremely valuable ecological services to humans that many urban coastal regions provide and enhance the revenue base to their associated communities.

Our proposed research was conducted in Pensacola Beach, Florida with current beach management groups on local and state levels.
Project Focus: Area of Interest
Florida, with the longest coastline in the lower 48 states, has approximately 1,350 miles of coastline not including the numerous inland rivers, bays and estuaries, and depends heavily upon its water tourism and recreation industries.
Water quality is a primary concern because nearly all of coastal Florida is used for recreation in one form or another.

Public concern over microbial contamination of recreational waters has increased in recent years.
In 2000, Congress passed the Beaches Environmental Assessment and Coastal Health (BEACH) Act to address the increasing problems of beach contamination.
The Beaches Environmental Assessment and Coastal Health (BEACH) Act of 2000 requires each state and territory with coastal recreation waters to adopt health-based bacteria standards that are "as protective of human health as" EPA's 1986 criteria for bacteria.
What are the Issues?
Telepath Systems 6
What are fecal coliforms?
• Total coliforms (A class of rod shaped bacteria) are commonly occurring bacteria that live in digestive tracts. Fecal coliforms are the fraction of total coliforms that originate in feces.
Where do they come from?
• Fecal coliforms originate from sewage, animals, and agriculture (via
livestock and the practice of spreading manure as fertilizer).
Telepath Systems 7
Why are they important?
It is important to monitor these bacteria because they are indicators the
presence of other pathogens (bacteria and viruses) that can harm human
well being. Particularly to people engaging in water related activities like
boating, swimming, fishing.
Telepath Systems 8
How can they harm humans?
• Fecal coliforms are important to humans because they can cause infections, dysentery, hepatitis and various forms of gastroenteritis.
How can they harm the environment?
• As with all bacteria, if there are large amounts of organic matter,
they will decompose it and use up all the oxygen in the process. Low
oxygen (hypoxia) or no oxygen (anoxia) in the water causes the
death of marine life.
Telepath Systems 9
What is currently done to monitor fecal coliforms?
• Various Government, State, and Local agencies actively perform
assays to detect total and fecal coliforms. These are performed on
scales ranging from quarterly to bi-weekly.
Telepath Systems 10
How can monitoring be improved in the future?
• It has been found that there is a strong correlation between rain fall
events and high bacterial counts. Influx of organic matter to the
water nourishes these bacterial communities. Rain also increases
turbidity due to materials carried in runoff as well as resuspension of
particles already in the water.
Telepath Systems 11
How can monitoring be improved in the future?
• Turbidity sensors, that measure back scatter, can be deployed on remotely operated buoys. These buoys can stream (via satellite) real-time turbidity data to the end user. The end user can use this to correlate turbidity to fecal coliforms and offer an early detection of risk to public waters.
• Because rain events occur so sporadically it is more appropriate to have a small sampling interval as opposed to bi-weekly. This way bacterial threats can be monitored on a daily to hourly basis.

EIM Sensor has partnered with the EPA gulf ecology lab to develop spatially
enabled decision tools that combine in-situ measurements with NASA MODIS
datasets.
